Description (female holotype only)

LENGTH. 14 mm.

COLOUR. Mostly metallic blue-black, palpus distally yellowish-brown, margin of clypeus brown. Legs and abdominal tergites 3–7 brown, except for white fore tarsomeres 1–3, yellow-brown fore tarsomeres 4–5 and ventral base of tarsomere 1, white hind femoral base and white medial bands on mid and hind femora. Notum, including postnotum, microtrichose, with two broad longitudinal dorsocentral microtrichose silvery vittae. Wing entirely black.

HEAD. Epicephalon striate-rugose, paracephalon shiny and smooth. Frontal vitta diamond-shaped, black, tapered to dorsal, lateral and ventral points, extending across entire frons. Postocellar bristles closely spaced and cruciate, inner and outer vertical bristles strong; upper fronto-orbital inserted at level of ocelli; one large lower frontal orbital bristle inserted well below border of epicephalon. Frons contiguous with antennal socket, antennae separated by width of antennal socket, upper face broadly raised; parafacials, gena and lower face strongly microtrichose, subantennal areas shiny, middle of face flat and microtrichose. Clypeus directed anteriorly, meeting face at an angle of about 100°, shiny medially, laterally microtrichose. Postocciput with uniformly small setulae.

THORAX. Dorsocentral and scutellar bristles broken on unique type. Katatergite slightly swollen, but without median process. Postpronotal lobe uniformly microtrichose, except for anterior bare margin, with a few scattered fine setae. Cervical sclerite with a small anterior lobe divided into an anterior bare part and a posterior microtrichose part by a vertical carina, and with a large microtrichose and strongly convex posterior lobe. Vertical row of katepisternal bristles brown, other katepisternal bristles pale yellow. All coxae with an anteroventral row of black setae.

ABDOMEN. Abdominal segment one and base of segment 2 petiolate, T1+2 twice as long as T3. Bursa subquadrate, with a distinct and distally differentiated ventral receptacle at base; bursa distally-dorsally extended into a long common spermathecal duct, single duct arising from side of common duct near apex, paired duct arising from apex. Paired duct relatively dark and sclerotized, short, uniform in width, weakly striate, branching into two distally convoluted stems, each leading to a large, ringed, pipe-like spermatheca. Single spermatheca elongate, similar to duct but separated from duct by a constriction.
